Why are my BMW steering wheel controls not working?
There are many reasons that can disturb the function of steering controls in BMW cars. Here are the details:
Issue with wiring
The bundle of wires is present on the steering wheel control for their appropriate functioning. Due to issues in these wiring, you cannot control the different systems with these buttons.
When you press them, you cannot see any operation on the screen. The audio system is necessary for the cars while driving on the long route.
The wiring harnesses often go bad, and they cannot supply current to different parts for proper signaling.
You press the button, but the audio system cannot work, and you feel difficulty changing the different radio stations while driving.
It is a common issue that occurs in vehicles, and people’s journey becomes boring. The wirings also become bad when old and cannot function properly.
In addition, their connected joints and assembly also become faulty, which can cause the issue.
The fuse is also present in the steering control of the BMW for the protection of wiring. The wiring also becomes overheated when you drive the cars for a longer time.
The overheating in this section will cause the fuse to blow out. When these fuses are blown out, the button on the power steering wheel will not work appropriately.
The horn is also present in this system which also stops working sometimes.
Sometimes, the fuses are blown out due to an excessive supply of electric current in wires because of faulty electrical circuits.
When the horn button stops working, you cannot alert the incoming person.

Faulty coil ring cartridge
The coil ring cartridge is present in steering wheel controls that are helpful to connect the wires.
These coil rings are important because they connect the different wires with the steering wheel. When these cartridge rings become old, they become out of function.
After some time, you have to replace them; if you are not doing so, it will cause insufficient working of these buttons.
The coil cartridge cause disconnection of wires which are unable to supply power to perform various functions.

The batteries are the major power supply source for every car to work. Without these batteries, the various systems cannot perform their function accurately.
When the batteries cannot provide sufficient power and become dead, the steering wheel controls systems cannot work.
Due to the poor supply of batteries, the light is also flickering on the dashboard because they cannot catch the signals from the buttons.
The batteries will also disconnect when their terminals become rusty and do not supply power.
In addition, the level of the low electrolyte and overheating will also increase the malfunction of batteries.
Many people also complain that it is difficult to attach them accurately when disconnecting the cars’ batteries for maintenance.
When the batteries and their terminals are not attached, the power supply will automatically cut down, and the buttons stop working.
The issues also come in the wiring of batteries which eventually cause poor power supply.
